Hi Nixon, In an isolated guest network you could create a guest instance and use it as a NAS? In a shared network you will have more flexibility in using existing NAS in the cloudstack provisioned guest instances.

ACS Portal: 10.10.40.252 NFS server: 10.10.40.250 KVM host: 172.16.0.100 (Have two network interface cards, one for private use (cloudbr0) and the other for public use (cloudbr1)) ACS Management Range: 172.16.0.10–172.16.0.50 (cloudbr0) ACS Public Range: Public IP RANGE (cloudbr1) I had trunked KVM Privet NIC to talk to the ACS and NFS subnets. So through 172.16.0.0, I can communicate with the 10.10.40.0 network. When I launch a VM with an isolated network of 10.1.1.5, it creates a VR with 3 NICs (eth0: 10.1.1.1, eth1: control, and eth2: public). I need to mount an NFS server with this guest VM. While checking the VR route, I can see the default route to the public NIC. Through that NIC, I won't get the 10.10.40.250 system as it passed out from KVM through cloudbr1. It is not advised to trunk KVM host cloudbr1 NIC and allow 10.10.40.250 traffic to route through the public network. What, in this particular situation, will be the best course of action? I'm eager to hear your thoughts. With Regards, Nixon Varghese
